4 claims. (c1. 269-156) This invention relates to a stand or supporting device, and more particularly to a stand for supporting a chassis such as a radio or television chassis while the chassis 1s being worked on or repaired.

An important object of the present invention is to provide a stand wherein chassis of different sizes can be readily supported therein, and wherein the stand is adjustable so that thechas'sis or other member being wonked on can be moved to different positions so as to permit the repairman or other person to readily gain access to all parts of the chassis. 1 n

A further object of the inventlon 1s to provide a stand which can be adjusted in size to accommodate chassis of In the laccompanying drawings, forming a part of this' application, and in which li'ke numerals'are used todesignate like parts throughout the same.

Figure 1 is a front elevational View illustrating the chassis stand of the present invention.

Figure '2 is a top plan view of the chassis stand.

Figure 3 is an end elevational view of the chassis stand.

Figure 4 is a perspective view illustrating one of the plates and its associated parts.

Figure 5 is a fragmentary plan view illustrating a bar and rod which are connected together.

Figure 6 is a perspective View illustrating certain constructional details of the device.

Referring in detail to the drawings, the numeral 10 indicates the stand or supporting device of the present invention, and the stand 10 is adapted to Ibe used for supporting a chassis such as the chassis 11, and the chassis 11 may be a radio or other piece 'of equipment being worked on, the unit 11 including the usual knobs 12 and 13 which can be used for turning the radio en and oi or for changing stations or the like.

As shown in the drawings, the stand 10 includes a pair of spaced parallel similar support members 14, and extending upwardly from each support member 14 and connected thereto by a suitable securing element 16 is a vertically disposed standard 15. Extending upwardly from each standard and adjustably connected thereto is a vertically disposed post 17, the post 17 being provided with openings 18 whereby a suitable securing element such as a bolt or pin 19 can be extended through the standard 15 and through one of the openings 18 whereby the post 17 can remain immobile in its various adjusted positions.

`Secured to the upper end of each post 17 is a horizontally disposed strap 20. As shown in Figure 6, there is provided body members 28, and each body member 28 insimple plurality `of spaced apartopenings or apertures 22. `VEx*- Y cludes yan intermediate bearing portion 30, the numeral 31 tending from an end of the collar 21 'and secured thereto or formed integral therewith is an arm 23, and the arm 23 includes iirst and second oifset portions 24 and 25. A

crosspiece'26 is larranged at right angles with respect totv the portion 25 and secured thereto, and the crosspiece 26 is provided with openings 27. The crosspiece 26 is arranged immediately above the strap 20. There is further provided a pair of similar top members which are indicatedr by the numeral 29, and each vtop member 29 inindicating securing elements such as bolts or screws which extend through the ends ofthe top member 29 and through the openings 27 in-the crosspiece 26,v and through the corresponding strap 20 arranged therebelow; Y

There is further provideda pair of spaced apart'horizontally disposed rods 32, and the rods 32 are rotatably supported by the bearing portions 30 and collars 21.V Each rod 32 is provided with a plurality of spaced apart openings 33, and a screw member 34 is'adapted to extend through an opening 22 in the collar 21 and through one of the'openings 33 in the rod-32 so that the rods 32 can be maintained vlocked orV stationary after they have been adjusted to their desired position. Y

Arranged -at right angles withrespect to the inner end of each rod 32is a bar 35, and the bars 35 are connected to the rods 32-as`at 36. Mounted on each bar 35 is a pair of spaced apart cylindrical sleeves 37, and the numeral 38 indicates set screws which extend through the sleeves 37 and engage the bar 35.- Secured to each sleeve 37 is an L-shaped lbracket or lug 39, and a plate 40 is securedto each bracket 39, as for example by means of rivets. Hook members 41 extendfrom the ends of the plate 40, land another'hook member 42 extendsfrom an edge or side of the plate 40, Figure 4. The numeral 43 indicates spring members or coil springs which are connected to certain of these hook members so that the spring members will insure that the plates will exert sutiicient pressure to hold Vthe chassis 11 therebetween.

From the foregoing, it is apparent that there has been Y provided a stand which is especially suitable for use in supporting members such as the chassis 11, andthe chassis 11 may form part of a radio or television set'or the like which is being repaired or worked on. According to the present invention, the chassis 11 is positioned between the four plates 4i), and with the springs 43 connected to the hook members 41, it will be seen that sufficient pressure willbe exerted by the plates 40 on the chassis 11 so as to hold ^the chassis 11 in its proper position. It is to be noted that when the chassis 11 includes knobs such as the 1 knobs 12 and-13, the spring members 43 will be spaced from the Iknobs so that the chassis can be properly sup ported.. In those units or chassis which do not have such an arrangement of knobs 12 and 13, then spring members suchV as the spring members 43 may be connected to the hook members 42.

cludes a cylindrical collar 21 which is provided with a ,It is to be noted that the stand of the, present invention is capable of adjustment in several different manners. For" example, the eiective height of the stand can'be varied by removing the pins 19 so that the posts 17 can be raised in the standards 15, and after Vthe posts 17 have been moved to their desired upV or down position, the pins 19 are again inserted through the standards 15 and through a registering opening 18 in the post 17 so that the posts 17 will be locked in its proper adjusted position. Furthermore, by removing the pins or screws 34 from the registering openings 22 and 33, it will be seen that the rods 32 can be rotated in the collars 21 and bearings 30 and after the rods 32 have been shifted or rotated to their proper or desired position, the screws 34 are again inserted through an opening 22 and the registering opening 33 so that the rods 32 will be held immobile in their adjusted v 2,946,584` Patentedduly 26, 1960V 9.a position. This rotation of the rods 32 will cause the entire supporting structure which engages the chassis 11 to be rotated so that for example the parts can be moved from the solid line position of Figure 3 to the dotted hne position of Figure 3, and this permits the repairman or other persons to readily gain access to all parts of the equipment 11. Thus, as the rods 32 rotate,the bars 3S are moved since the bars 35 are connected as at 3'6 to the rods 32. Furthermore, the bars 35 have the sleeves 37 connected thereto by means of the set screws 38, and the sleeves 37 are connected to the plates through the medium of the brackets 39. Also, by loosening the set screw 38, the position of the sleeves 37 on the bars l3S can be adjusted and this permits the plates 40 to be adjusted to receive chassis of different width `or sizes. Since the support members 14 can be moved towards andaway from each other, and since the spring members 43 are capable of extension or retraction, it will be seen that chassis or units 11 of different lengths can also be accommodated or received. The springs 43 will exert sufficient tension on the plates 40 so that the chassis 11 will be held firmly in its adjusted positions.

The parts can be made of any suitable material and in different shapes or sizes.

The springs 43 will prevent the chassis from slipping ont of the stand, and it is to be understood that the stand of the present invention can be used for supporting any desired type of equipment. The parts may be made of light weight material such as aluminum where feasible, and the stand is adjustable and adaptable for use with various pieces of equipment such as radio, television and electronic test equipment. Due to the adjustability of the stand, the user can readily gain access to the various parts and wherein better illumination can be provided, and also damage to the set will be minimized or prevented. Also, the rods 32 can be shifted longitudinally through the bearings 30 and collar 21 by removing the screw member 34, and this provides another adjustable feature. The stand is ruggedly constructed and strong so that heavy loads can be supported, and the sides of the springs 43 can be varied as desired.

The above description of the invention is for illustrative purposes only and it is understood that modiiications may be made in the construction within the scope and spirit of the following claims.
